Overcurrent/overvoltage protection
Each DC power supply circuit has an overcurrent protective function
and overvoltage protective function. This prevents a power supply
circuit failure by automatically interrupting the output voltage when
anomalies such as a short develop on the loads that result in
overcurrent flow or abnormal voltage.

Note
Protective functions remain active for two minutes after activation.
Wait for at least 2 minutes to turn the power back on again.
Wait for at least 2 minutes to turn the power back on again.
If this function is activated and no DC voltage is output from the
low-voltage power supply circuit:
low-voltage power supply circuit:
1
Turn off the power switch (SW6).
2
Unplug the power cord.
3
Resolve the anomaly on the load.
4
Turn the power switch (SW6) on again.
